Built Nolo, a WhatsApp-native AI scheduling assistant, entirely solo using AI-assisted development tools as primary collaborators. Architected the production backend on Python/NestJS with AWS ECS Fargate, PostgreSQL, MongoDB Atlas, Redis, SQS, and CloudWatch observability with zero-downtime rolling deployments. Designed agentic workflows using OpenAI GPT-5-mini with function calling, structured outputs, guardrails, and RAG over MongoDB Atlas vector search across 25+ languages. Integrated Google Calendar API, Microsoft Graph API, Apple Calendar (CalDAV), Zoom, and Google Meet. Implemented Stripe billing with multiple tiers, idempotent webhooks, dead letter queues, and payment reconciliation audits. Drove growth from launch to 5,000+ users and represented the company at GITEX AI Asia 2026 through investor/enterprise pitching.

Modernized a legacy Flight Information Display System into a scalable multi-airport platform using NestJS, React, MongoDB, and GCP Pub/Sub microservices. Built a Flight AI Assistant using RAG over live flight data with MongoDB Atlas and OpenAI APIs to support natural-language querying and reduce manual terminal lookups. Deployed and managed production infrastructure on GCP with high availability, real-time data distribution, and horizontal scalability, enabling replacement of the legacy system across multiple terminals.

Designed and deployed agentic automation workflows for e-commerce customer experience (order tracking, recommendations, and support), reducing manual customer interactions by 70%. Built conversational agents using OpenAI APIs with multi-step reasoning and function calling via WhatsApp Business API and Twilio. Integrated GoHighLevel (GHL) CRM APIs to automate lead handling and client communication pipelines.
